360 degree continuous rotation potentiometer for compass
Hi Guys, I'm making a gyro compass and needed a potentiometer to monitor rotation of a dc motor (continuous rotation servo). This is a shaft driven 10kΩ potentiometer, but unique in that it has twin wipers on a single resistive element (4 connections to the pot). The wipers are opposed 180° so one of the wipers is always on the resistive element. I am connecting both wipers as voltage dividers to individual Arduino pins. They cost about $5 each. ALPS RDC803001A. I hope this helps someone.
